Document Summary
Altered reproductive function: female reproductive function: external genitalia: Mons pubis, labia majora/minora, vestibule, skene glands/bartholin glands for lube: female reproductive function: internal structures. 1. inner endometrium: sloughed during menses: muscular myometrium, outer perimetrium. Ovaries: estro/progesterone/andro: stoma: supporting tissue, interstitial cells: secrets estrogen, follicles: ova/germ cells, corpus luteum: forms after the ovum has been released from ovarian follicle. Pregnancy: hcg from zygote which acts on cl to maintain progesterone/estro. Posterior pituitary, contractions and milk ejection (let down during lactation) About 10 primary inactive follicles are stimulated by fsh/lh and become active secondary follicles. One becomes dominant and the rest atrophy (atretic) Dominant continues to secrete estrogen which alerts pituitary to stop fsh production ( fsh) Lh levels remain elevated and reach a lh surge (at the peak of estrogen secretion from the dominant follicle) This lh surge allows the follicle to be released (ovulation: luteal phase: Ruptured follicle forms a corupus luteum (cl), which secretes estrogen/progesterone.
